Well done Stubby - about time too
And very well done for getting them out of the wet - does show the need for regular checks as you were doing.
They will be fine as call birds but personally I would keep the smaller one. My experience is that they are more effective somehow.
As for pets ? I don't think it's legal to make any wild bird captive as a pet, although, as in the case of call birds, the law make some exceptions for specific purposes.
